Description
Technical field
The utility model relates to the casting of a kind of magnesium alloy and use the fluid switch, specifically is a kind of being opened and fluid switch by conducting oneself with dignity and sealing by external force on the magnesium alloy cast tubes that be placed in.
Background technology
At present, promptly the cast switch of pump of the fluid switch of public magnesium alloy casting usefulness, the start and stop by control casting pump come and then whether control front end cast tubes gets magnesium liquid.Certainly because the casting pump is often squeezed into liquid magnesium alloy earlier in the transition bag on the cast tubes, in the casting cycle of reality, general dependence is manually fallen or is lifted that the transition bag comes and then the outflow of control magnesium liquid and stopping.Wherein the former is owing at the numerous use casting switch pump of reality casting operation intermediate frequency, certainly will strengthen the loss of casting pump motor, thereby shorten the casting pump life-span; And latter's automatization level is relatively low, and workman's amount of labour in practical operation is big; Again because the workman is when putting down the casting of transition bag, owing to still have one section long tubing string between transition bag and the cast tubes liquid outlet, when just having caused magnesium liquid to pour mould from cast tubes, this can produce bigger impact to the magnesium liquid liquid level that has existed in the mould, make magnesium liquid instability, easily contact and oxidation, influence end product quality with air; And when the workman lifted the transition bag, liquid outlet can not stop the outflow of magnesium liquid again at once, and magnesium liquid height just can not get effective control in the mould, has also wasted magnesium liquid.And the sealing between transition bag and cast tubes also often can not get ensureing.In a word, control the mode of the fluid of magnesium alloy casting cycle with the transition bag, the artificial disturbance factor is many, and is wayward, increases difficulty to plant maintenance simultaneously.
Summary of the invention
The purpose of this utility model be to society provide a kind of simple in structure, cost is low, replacing is convenient, outer power is opened and the fluid switch on the magnesium alloy cast tubes of being used for of the sealing of conducting oneself with dignity, and it has avoided frequent switch casting pump the loss of pump motor and manually-operated transition bag to be controlled loaded down with trivial details, the difficulty and the defective of fluid.
In order to achieve the above object, main technical schemes of the present utility model is: the fluid switch is used in a kind of magnesium alloy casting, it is characterized in that being made up of overcoat and central plug, overcoat is a hollow pipe, central plug is positioned at overcoat, and its top cooperates with the overcoat underclearance, and the overcoat outlet is stretched out in the bottom.
In the practical operation, overcoat top is connected with cast tubes, goes out mouth down; Central plug is positioned at overcoat, because deadweight sinks, thereby cooperate with the overcoat bottom can blocking pipeline on its top; Certainly make the shaped upper part of central plug of the present utility model and the shape of overcoat lower lumen be complementary, for example overcoat top is cylindric, bottom and is coniform, the central plug shaped upper part for overcoat lower cone shape inner chamber be complementary coniform, make like this when the central plug deadweight is sunk, can be close between the opposite face of compatible portion, further guarantee the sealing of fluid switch.
When needing casting, the control lift cylinder is fallen cast tubes, and the latter half of stretching out the overcoat outlet when central plug stops to descend when touching die bottom plate, and overcoat continues to descend, and its Lower Half is untied with the central plug first half and cooperated, and produces the gap, make pipeline unimpeded, magnesium liquid just flows out smoothly; Control cylinder lifting cast tubes when needs are closed, central plug are again because deadweight sinking blocking pipeline.
The utility model is an independent assembly in the magnesium alloy casting system, have simple in structure, good airproof performance, the advantage changed of convenient disassembly at any time; Because it can rely on deadweight to close, stop the fluid of cast tubes, avoided the loaded down with trivial details loss that reaches equipment of manual operation in this process; Simultaneously since design feature of the present utility model make cast tubes must go deep into mould and carry out casting, and magnesium liquid is from mold bottom injection mould slowly, the back inject mould magnesium liquid since the overcoat outlet immersed magnesium liquid and can not contact with air.Therefore can not cause bigger impact to the liquid level of magnesium liquid in the whole casting cycle or make magnesium liquid seethe instability, effectively prevent from the oxidation of magnesium liquid to have improved product quality.It is suitable for use on the higher magnesium alloy casting equipment of some automaticities, has improved production efficiency when saving the hand labor amount greatly indirectly.

The specific embodiment
The shape of overcoat of the present utility model and central plug can design according to concrete requirement, shown in the drawings is a kind of preferred embodiment of the present utility model: this magnesium alloy casting is made up of overcoat 3 and central plug 2 with fluid switch 1, that overcoat 3 is that top is is cylindric, the bottom is cone shape hollow pipe, central plug 2 shaped upper parts for overcoat 3 lower cone shape inner chambers be complementary coniform, central plug 2 Lower Halves are outlet cylindric and that can stretch out overcoat 3.
During practical operation, overcoat 3 tops are connected with cast tubes 4, and central plug 2 places overcoat, because self gravitation central plug 2 is sunk, its upper cone shape and overcoat 3 lower cone shape inner chambers coupling are close between the opposite face, block pipeline, the outlet that while central plug 2 lower cylindrical bodies stretch out overcoat 3.When the control lift cylinder is fallen cast tubes 4, fluid switch 1 is in company with descending, when central plug 2 lower cylindrical bodies touch die bottom plate and during stop motion, overcoat 3 relative central plug 2 continue to descend, central plug 2 upper cone are relative with overcoat lower cone shape inner chamber to break away from cooperation, produce the gap, thereby make pipeline unimpeded, magnesium liquid is flowed out smoothly.When closing, only need the control lift cylinder that cast tubes 4 is lifted, central plug 2 lower cylindrical bodies break away from die bottom plate, and central plug 2 is again because deadweight decline closing pipe line.
Because the said structure characteristics of present embodiment make cast tubes must go deep into mould and carry out casting, and magnesium liquid is from mold bottom injection mould slowly, the back inject mould magnesium liquid since overcoat 3 outlets immersed magnesium liquid and can not contact with air.Therefore can not cause bigger impact to the liquid level of magnesium liquid in the whole casting cycle or make magnesium liquid seethe instability, effectively prevent from the oxidation of magnesium liquid to have improved product quality.It is suitable for use on the higher magnesium alloy casting equipment of some automaticities, has improved production efficiency when saving the hand labor amount greatly indirectly.
